nventor y I r V I Attorneys i To! ail l w ko mizt Be it known; that I, HARRY THA'SVKERY, a citizen of'the nited States, residing at Sidneyginf-the county of Kennebec andState efyMain-e, have? invented a {new and useful.

(lrowJack, 'jof which}. the, "followingv is ma specification. p I

crow jacksl i H V I i ';Th91 obj ectf of the present? invention is to fprovide a'crow jackywhioh will simulate to l 'HJCQitainT extent 1 the movements .ofia human being and will present theexternal-appean,

- ance' thereo'fso' as to V scare or frighten crows or F othe'r birds:

j A jfurthe r object to: provide; ldevice fwhichhwill present" the; appearance of a hue man being and will be jprovided with paddles located at thegextremities of out stretched armsand which will be rotated: by,

the "wind and which are connected. by a 'shaft,f 'which"flatter is. designed to oscillate the head.

I A further object 15,150 provide crowjack,

pivotallyseoured uponan upright which extends along one leg'and with-the other leg extended and acting in'the capacity of a vane tohold the jack in certainfand definite relation with reference to the wind so that the paddles located 5 at the extremities of the armswill be rotated with the result hereinbefore, referred to. f

' With'the foregoing an other objects in view which will i 5 In the"drawingsaccompanying this spec if: 4'5 "fication and"forming-a part thereof, the pre-" I ferredembodiment f appear as the description proceeds, the invention resides in the combinationand arrangement of parts and in the details of construction hereinafter describ'ed and claimed, it" being Qunderstood that changes in the V invention herein jdisclosed can be-fmajd'e I With'in'the'scope of what is claimedywith-f outdeparting from the spiritrof the inven precise embodiment of "the tion., 1

this connection it is to .be' noted however,

that the exact mounting tmay vary as local condltlons and circumstancesjmay warrant.

Pivotally or rotatably mounted: upon the rod 5 is the frame whichincludesthe. postfi whereby itfis held in auverticalymanner.

iiENT E- bearings 7 Rigidly secured tothe post, 6 and adjacent the upper extremity is the crossbar 8 along which extends the-horizontalshaft 9.. The

cross bar 8iis providedwith the bearings '10 which. revolubly support the shaft 9 and to which. shaft at its extremities areusecured the blade'cai'rying bosses 11. A singleblade is secured to" each "of the blade carrying bosses and project in opposite directions and are aclaptedito-berotated by the force ofthe Wind when blowing in a direction parallel tolthe longitudinal axisyof the shaft 9. The bracket 12 is rigidly secured to the cross bar 8 and is bifurcatedtat its upper front extremity as at 13 and between the projecting prongs of which is pivotally secured the lever 14. which carries at its upperCextremity the head-like block 15.' Thus the head-like blockis adapted to pivot about the'en'dof the bracket12 and when so oscillating, taken in connection with the waving of theblades will simulatethe motionsof a human being to such an extent as to scare or frighten animals which may be in the immediate neighborhood. The: shaft 9 is provided with the cam 16 which is rigidly secured periphery of which contacts lnor'der' to insure that the lever will remain the peripheral gidly fixed to the frame. The spring arm 17 also performs the desirable function ofholding the clothing of the In order to'inakeithe devic'e present the appearance of' a person, the outstanding leg ISisprovided rigidly secured'to and forming a part of the frame and it also performs the desirable feature of acting'as a vane,

keeping the paddles 19 in the ind. The

leg 18 forms a part of or may be rigidly se- In order to I strengthen the entire structure, a cross strut is provided secured to the post .6 andleg 18 and also to a. second fragmental'post 6'" Which is spaced in such manner that" the spring 17 will come centrally between the posts 6 and 6;

cured to the cross bar 8.

The lower extremities of thepost and leg 18 are shaped to illustrate a foot so as to maintain the'representation of a -person.- In

. fromrth'e upright vertical rod 5or'the same order for the device to fur'the'r simulate the appearance of a human-belng, arpairof trousers 21 are placed upon the post band leg 18, it being. noted that the same mayrbe accomplished :by raising the post 6 so that thezbearing Twill disengage and be removed I may: be accoinplishe'dby "splitting one of the 1 or other suitable means.- It is 35 trouser" legs and securely nailing the same to the post, A coat 22 is also buttoned around the central portionof the frame and is held from collapsing by the posts 6'and 6 and the sleevesof the coat extend out over the extremities of .the cross bar-'8; In order thatxthe coat may be secured to the crow jack, one of the sleeves is slit and the coat sleeve then securely held to the jack by nails to be noted that the paddle receiving bosses 11: maybe removed in order to assemble the coat upon the frame. 1Th'us as illustrated .in Fig. 1,

with a hat23 to complete tliemake-up, the device will-present all the appearancesof a 40 which may be; in the immediate vicinity.

The device is to be placed in corn fields or other .places which are to be protected against theravages of birds or animals. a

, imparted to thegfi-gure about a vertical axis A further featureis by the providingof' a single blade outstanding from each boss 11 and-by extending the two paddles in yopposite directions, an oscillatory motion 'Will be due to the varying and uneven centrifugal g eflicient Working of-the device, e

Thus the figure Wlll tend to oscillate about the vertical axis through limited arcs and which combined Withth aforementioned motions :provides forafn base, a frame, including outstand i ng 1 Having thus fully described my invention, What Iclai1nis: f
